Passport front cam & printing

Hey there, I have some question about the passport. I already had to send back 2 of them to Amazon, because on both, the front cam was very slow and laggy. I also did not find a working way for AirPrint or sth. like that.
Did anyone have the same issues?
I bought the premium version of printhand but although my canon printer was found, it did not start to print. Would be nice if someone could help me. I so love the passport more than my iPhone 5s, but these 2 things need to work.
